Café Bitcoin | Larry Lepard and Greg Foss on Japan as the Seminal Event, Credit as the Warning, and Why Timing Beats Everyone | Day 21 of 50
Épisode 662
mardi 11 août 2026 • Durée 01:31:53
Cory's argument about narratives. Journalists and bankers keep asking what the catalyst will be, but narrative follows price rather than causing it. Something moves because sellers are exhausted, and the reason gets fitted afterward. The only narrative that matters is Bitcoin being better money for eight billion people.
Larry Lepard on what actually moved. The debasement trade began in earnest last year, and it showed up first in gold and silver rather than Bitcoin because those are more widely understood. Silver quadrupling is the kind of thing that has essentially never happened before.
Japan is the seminal event. With Japan holding roughly $1.2 trillion in Treasuries, the US offered swap lines and rotated euro reserves into yen. What shook the gold market was the Treasury Secretary suggesting the existing facility should be larger. As Larry put it, a swap line is printing money, full stop.
A guest correcting his own AI. Larry noted the press had the facility's usage wrong and that AI had misled him too, so he went and read the Fed's own statements to establish it had not actually been drawn on. Worth noting as a method, not just a detail.
The 1992 parallel, corrected live. It was Warsh, not Bessent, who worked for Soros attacking the Bank of England. Thirty-four years later he is on the other side of that trade, in the Bank of England's role. Larry's thesis for the year is the unmasking of Warsh as a hawk, because the math will not let him be one.
The Fed has exactly two tools. It can mislead about inflation, and it can print. Larry's read is that we are currently in the first phase and last week signalled a move toward the second. He also explained yield curve control as what governments do when the bond market stops cooperating, with the post-war precedent as the template.
His own record is the caveat he volunteers. He expected massive inflation out of 2008 and a cascade from Silicon Valley Bank, and was wrong both times. The people running the system are good at kicking the can, so the honest position is direction with no date.
The two-tier system he expects. The dollar remains the unit everyone transacts in, gold displaces Treasuries as the reserve asset, and Bitcoin sits alongside before eventually supplanting gold over years, not days. It is already visible in oil sold for yuan and immediately swapped into physical gold.
Greg Foss on where trouble announces itself. Every recent crisis began in credit rather than equities, and private credit is where he is watching now. His trader's version: equity investors ask how much they can make, credit investors ask how much they can lose. Credit is the first smoke in the theatre.
And his structural objection about treasury companies. He takes issue with perpetual preferred shares being described as credit, because a perpetual has no maturity and no principal repayment, so its running yield cannot be compared to a bond's yield to maturity. Retiring that stack at scale would mean selling Bitcoin, which was never the strategy.
Café Bitcoin | Jeff Ross on Energy Money, Why Abundance Still Needs Scarcity, and Study Before You Stack | Day 20 of 50
Épisode 661
lundi 10 août 2026 • Durée 39:42
The theme was looking forward After two brutal weeks the room turned to what comes next, set up by a listener's observation that the philosophical Bitcoin conversation which drew people in around 2020 had gone quiet for years and is audibly back
Why the guard dropped Phillip framed Coldcard as a psychic blow because it was the standard for personal sovereignty, and the harder question is why the surrounding behavior got a pass. Isaiah added that a friendly administration lulled people into "we've arrived" and a foot off the gas
Suz's line is the sharpest in the episode "I don't tell people to buy Bitcoin anymore. I tell them to study it," because only genuine understanding stops someone panic-selling an eighty percent drawdown
And she named the drift Keep Bitcoin separate from the leverage games and financial engineering, and drop the hero worship and Wall Street cheerleading, particularly among people who pride themselves on critical thinking
Dice rolls may not be the destination Swan engineer Steve is unconvinced that rolling your own entropy is the paradigm going forward, citing Luke Childs' time-locked proposal as proof that one week of focused attention already produced something worth exploring
Jeff Ross on why he came back He left in 2024 at what he called peak clown world and returned because the Overton window moved and macro conversation had vanished from Bitcoin rooms. He was emphatic that nobody should follow him and that nothing he says is advice
Energy money, his signature thesis The dollar began as commodity money redeemable for gold, and Bitcoin is commodity money whose commodity is energy itself. Tesla, Ford and Buckminster Fuller all reached for the same idea, and proof of work is what makes it real
He rejects the abundance argument flatly Told money may not matter within fifteen years, he called that top-of-hype-cycle talk most often heard during fundraising. Sunlight is free but panels, batteries and rare earths are not, and economics will always be economics
Cory on the only real asymmetry Strategy is legible to him and operations are not, but cryptography is the one thing genuinely on our side: the ability to make something unbreakable by an adversary with millions of times more power. His conclusion is that early-nineties cypherpunks may turn out to be the pivotal figures
Café Bitcoin | Slay Your Heroes, the Fourth Turning, and Certainty Lowers Your Guard | Day 17 of 50
Épisode 659
jeudi 6 août 2026 • Durée 01:25:48
Suze's Forbes piece, and the question under it. Her Telegram reporting found a persistent identifier that survives restarts, network changes and borders, with the credible risk being targeted surveillance rather than mass tracking. Her real question: why is don't-trust-verify never applied to companies and personalities inside Bitcoin?
The confessions, and Cory's calibration. American HODL admitted he bought a Coldcard largely as a badge of Maxi Club membership, and Odell described being pulled into a cult of personality. Cory's distinction: someone who bills himself as a technical expert and reviews products carries responsibility a self-described bullshitter does not.
He also warned against the new bad heuristic. Treating abrasiveness as a proxy for bad code fails immediately: Core and Blockstream are full of people who read as cocky and their code is sound. He credited NVK as a genuinely good educator while calling the outcome inexcusable.
Brandon Quittem: deep in it, not at peak. Maximum wealth inequality is a classic Fourth Turning signpost, and the post-war institutions are a shell of themselves without anyone needing to be malicious. He held his own confidence low throughout, calling the framework a rough way to squint at the world.
His bet on the climax. Not a head-to-head with China, which a hyperglobalized economy makes unlikely, but a Cold War 2.0: proxy and economic war, trade policy, supply-chain fights, plausible deniability, and zero-day attacks on each other's infrastructure.
AI through the Fourth Turning lens. The authors would say technology is always arriving and the variable is how the generational mood receives it. Facebook landed because millennials were the sharing archetype; Gen X would have refused it. He calls AI pure leverage with no clear direction.
Horseshoe theory, and Bitcoin as the through line. Answering Suz on where left and right even are now: both extremes arrive at authoritarianism from the same wealth-inequality catalyst, which is why Bernie and Trump were popular at once. Bitcoin is what pushes back on both.
He retracted his own timeline live. Five years ago he would have called a Bitcoin standard likely by 2030 and now says that was far too aggressive. A First Turning looks like exhaustion, inequality easing, culture getting more boring, and it may only be visible in hindsight.
Café Bitcoin | Guy Swann and Yan Pritzker on Coldcard, the Asymmetry of Defense, and Privacy | Day 16 of 50
Épisode 658
mercredi 5 août 2026 • Durée 01:12:00
Guy Swan on learning the wrong lessons. The takeaway circulating is "go with the biggest company," which forgets Mt. Gox and FTX and everything else proving size is not safety. His analogy: when a libertarian politician betrays you, libertarianism didn't break, you got scammed.
He wants a rule that works forward. His sharpest point: "I don't want a rule that only works in hindsight." Anyone can now point at the source-available license. The useful question is what indicator predicts the next failure before it happens.
His own heuristic broke in both directions. He had trained himself not to dismiss builders for being abrasive, and now concludes that for security specifically, a maintainer who attacks people reporting problems is telling you something. Yan Pritzker paired it with the engineering version: without a culture of safety, people stop surfacing mistakes.
James O'Beirne's tripwires. He seeded wallets on-chain carrying graduated entropy over broken Coldcard seeds, five dice rolls, ten, fifteen, one and two-word passphrases, as bait. The bare seed was swept within an hour and nothing else has moved, mapping attacker capability live.
The red team's numbers. Rob Hamilton and Calle have scanned over 300 repos and spent roughly $40,000 on tokens in two days, finding critical vulnerabilities at about one per person per hour. OpenSats is now funding most of that budget.
Every company needs an agentic security pipeline. Yan's argument: agents are non-deterministic, so one scan proves nothing. The real work is harnesses that find, test, distill and reproduce on a loop. Swan has been building this for six to twelve months.
The asymmetry is the whole problem. Attackers need one vulnerability, defenders need all of them, and the economics favor the attacker. Some have been paying up to 90% of stolen funds in fees to get transactions mined quickly.
A fake Coldcard desktop app is circulating. No such application has ever existed. Trezor reported a phishing spike since disclosure, and a counterfeit Wasabi wallet reached an app store. Nobody legitimate asks for recovery words, and unsolicited migration instructions are always hostile.
He calls the bug exotic: entropy wasn't weak, it was switched off entirely. Scans across the popular hardware wallets show correct and consistent entropy use, so he thinks this specific failure is unlikely to recur elsewhere.
Café Bitcoin | Self-Custody Is Not Dead, the Custody Spectrum, and Owning Is Not Operating | Day 15 of 50
Épisode 657
mardi 4 août 2026 • Durée 01:17:38
Dice rolls are now confirmed safe. Portland HODL published a full verification, independently cross-checked by James O'Beirne, Block's engineering team and Rob Hamilton: the Coldcard did use dice entropy rather than falling back to the pseudo-random generator. Fifty or more rolls was sufficient.
Still rotate anyway. The prevailing view on the show was that dice-generated seeds are safe but worth rotating as hygiene. Separately, no other hardware wallet firmware vulnerability has surfaced yet from the red-team sweep.
The red team is scaling. Rob Hamilton's group, now joined by other Bitcoin developers, is pointing Kimi K3 and other frontier models at repos across the ecosystem. Critical vulnerabilities have been found and responsibly disclosed, none in hardware wallets so far.
Cory rejects the "always more to learn" framing. He argued that line doesn't apply here: the entire point of code securing assets is that there can be no mistakes that put those assets at risk. He gave two press interviews on the exploit.
The custody spectrum, with a chart in the nest. Cory laid out five positions: solo self-custody, guided self-custody via Swan Sovereign at $25 a month, collaborative multisig, delegated custody with OCC-chartered custodians, and multi-institutional custody, which Swan has been building since December.
The real gap is knowing how to use your wallet. Alec, who spent the weekend on client calls, found people holding large amounts in setups they could not operate. Getting Bitcoin off an exchange is not enough. Practice moving it more than once.
Jason on the false binary. People have been taught there is one right way to hold Bitcoin, and that it's the most esoteric one. His question: what is self-custody worth if you cannot move your coins in an emergency?
Zach Herbert of Foundation. Self-custody is not dead, and he framed this as negligence by a single vendor rather than an indictment of every maker. His takeaway is free and open source software, shared libraries and engagement with auditors. He calls it the worst event for committed Bitcoiners since Mt. Gox.
Boltz went dark. The Lightning swap provider shut down entirely, hit by automated attacks faster than a small team could patch, taking swaps in Zeus, Aqua and Blockstream's app with it. No user funds lost. Brady drew the line from Kimi K3's release through Coldcard to this.
Café Bitcoin | The Coldcard Timeline, Joe Nakamoto on the Fallout, and Open Source Must Win | Day 10 of 50
Épisode 656
lundi 3 août 2026 • Durée 02:30:56
A full forensic timeline. Brady traced it end to end: a 2018 MicroPython software fallback sat harmless for three years until March 2021, when Coinkite moved to Bitcoin Core's math library and silently bound seed generation to that fallback. Lopp notes the bug lived in the build system, not the main code.
Firmware 4.0.0 is the dividing line. Shipped March 17, 2021. Seeds generated before roughly March 1 are fine, and MK3 releases 3.2.1 and 3.2.2 were the last safe ones. Every default seed after that was weak.
It was flagged in 2021 and dismissed. Four months after the bad firmware shipped, someone publicly raised Coldcard entropy concerns. NVK's reply called it FUD and demanded a line in the code. That post is deleted; an archived screenshot survives.
The scope widened over the weekend. Coinkite added MK2 alongside MK3 and MK4, and confirmed Q and MK5 at roughly 72 bits rather than the expected 128. Independent analysis put the MK4 class nearer 50 to 60 bits in practice.
Dice rolls and passphrases do not cover everything. Nine other Coldcard features draw from the same broken generator, including message signing and deriving keys for other purposes. BTC Sessions confirmed an MK4 with a one-word passphrase was drained.
Scale, and Cory's proportion. Roughly 1,300 Bitcoin total, 594 in the first wave, with Chainalysis showing the highest-balance wallets targeted first. Cory noted centralized exchanges and lenders have lost about a thousand times more.
The chip-ID recovery hope is gone. Holders were told earlier in the week to keep their devices because a chip signature might prove ownership. Brady reported that has since been shown not to work as hoped, narrowing recovery further.
Vendor indictment or self-custody indictment? An audience question that framed the hour. Brady argued it is a challenge to upgrade toward multi-vendor multisig rather than a verdict on self-custody. One listener pushed back that the indictment already landed.
Joe Nakamoto from Europe. He found almost nobody in his circle affected, since Coldcard's loudest advocates were largely American and circular economies mostly run on Lightning. Bloomberg was the only genuinely mainstream outlet, and its coverage was fair.
Café Bitcoin | Coldcard Emergency: What Happened, Who's Affected, and What To Do Now
Épisode 655
vendredi 31 juillet 2026 • Durée 05:10:35
The event. A firmware flaw in Coldcard seed generation, disclosed the night before, let an attacker recompute private keys outright. By airtime, 594 Bitcoin, put at roughly $38 million on the show, had been swept from about 500 wallets.
The mechanism. Yan Pritzker and Swan engineer Steve: the device's true random number generator was present and working, but a March 2021 library change meant the firmware silently stopped using it, falling back to software randomness seeded from device ID and clock.
Why five years passed. The code looked correctly wired, the failure hinged on a build-time variable, and the output still looked random. Zach Herbert of Foundation said a researcher flagged something adjacent in 2022 without unraveling it.
Who is exposed. Only seeds the Coldcard generated itself. Imported seeds are safe, dice rolls are safe, a long passphrase saved people. MK3 is worst hit. MK4, MK5 and Q sit near 72 bits, costly to attack but not impossible.
Updating firmware does not fix it. Coinkite patched, including MK3, but the vulnerable seed is the problem, not the device. You must generate a new seed and move funds. The dice function was never affected and has now been audited.
Multisig is not automatically safe. If most keys came from affected devices, an attacker can try permutations, and spending publishes your public keys and invites an RBF race. Wicked pointed people to Portland.HODL for private broadcast through Slipstream.
The attacker looks unsophisticated. The sweep ran roughly 25 minutes into a handful of addresses, stopped at shallow address gaps, and queried a public node instead of running one. Block researchers identified that service, so there may be a lead.
The industry reckoning. American HODL called it a Paul Revere moment and demanded podcasters and former sponsors broadcast immediately. Reardon argued the industry spent three years arguing over the wrong priorities and got caught by an entropy bug.
Self-custody versus diversification. Wicked held that multi-vendor multisig with your own entropy beats any custodian. Joe Carlasare countered that every system rests on assumptions that eventually fail. Yan declined to preach one model, calling self-custody still very early.

Swan's Phillip Alexander and Brandon Quittem host Day 8 of 50 Days for Freedom: Telegram's auth key ID and the Russian server question; getting debanked for the word Bitcoin, from Wise to Bitcoin Policy UK; Michelle Weekley on Bitcoin ATM bans, shared Claude links indexed by Google, and AI agents with access to your email; and Brandon Quittem on shrinking drawdowns and the retail wave that hasn't arrived.
Café Bitcoin | Day 7 of 50: Daniel Batten on Bitcoin and Energy, Britain's Curtailment Bill, and Wealth Is Energy
Épisode 653
mercredi 29 juillet 2026 • Durée 01:23:57
Cory was out for a family wedding, so Brady and Philip hosted from his handle. Also new: a weekly recap song in a different genre each week, covering everything from the previous weeks of the show.
Daniel Batten on Cambridge's new number. Its updated assessment puts Bitcoin mining at 59.4% clean energy, against a global grid mix near 40%. Hydro is the largest single source. Full report expected later this year.
Sweden's grid used Bitcoin mining 11,000 times last year to absorb excess wind. Batten's point: operators call it flexible load, flexible compute, or data centers. Anything but Bitcoin mining. Six Brazilian energy companies are doing the same with stranded generation.
The best idea in the episode, and it's Batten's. A grid operator is incentivized to admit a problem, because saying so unlocks resources and doesn't destabilize the grid. A central banker never can, because the admission is itself the instability.
Batten expects the West to adopt Bitcoin as an energy solution before a monetary one. In the global South the monetary problems are existential already: banking access, storing wealth safely, remittances that otherwise cost up to 20%.
The Ethiopian dam. You cannot build half a dam, so it's sized for demand 20 years out. No transmission lines, no industry, no customer for the surplus. Miners paid roughly three cents per kilowatt hour and delivered over $100M in unexpected revenue.
Callum Wheeler of Renew Blocks on Britain's curtailment bill. £1.5B last year paying wind farms to switch off and firing gas nearer London instead, forecast to reach £7B by 2030. A new "demand for constraints" market is meant to fix it.
A near-blackout on June 23 reached the shadow energy secretary via control-room whistleblowers. Cause: unexpected air conditioning demand in Britain's fourth heat wave. Wheeler's pilot is mining co-located inside a Scottish Highlands hydro powerhouse, built for £2M and never switched on.
Susie Violet Ward spent 13 months chasing a BBC correction on a headline claiming every Bitcoin payment uses a swimming pool of water. No correction, and the undisclosed source was a central banker. Brandolini's law: refuting costs ten times what inventing does.
Café Bitcoin | Day 6 of 50: Lawrence Lepard on the Big Print, the AI Credit Crack, and The Math Ain't Mathing
Épisode 652
mardi 28 juillet 2026 • Durée 01:25:43
Lawrence Lepard on bear market psychology. Everyone is short-term, negative, and attacking each other over BIP110 and Saylor. His read: we are winning, this is the moment to get friends buying, and he expects much higher highs within 18 to 24 months.
The big print thesis. Lepard is watching the yen carry trade, a near-vertical Japanese 10-year, and the US 10-year at 4.70 with 5% as the Fed's red line. Druckenmiller-adjacent circles think Japan breaks first.
"The math ain't mathing." A roughly $2T deficit while total debt grew $3.5T in twelve months. Hank Paulson resurfacing after fifteen years to suggest a Fed break-the-glass program reads to Lepard as a trial balloon for the big print.
Reading Kevin Warsh. Lepard's take: Warsh is abandoning the Phillips curve for a supply-side inflation story, talks like a balance-sheet hawk for the bond market's benefit, and will likely cut in September. Fed governor hawkishness is kabuki.
The AI credit crack. Cory: Nvidia credit default swaps blew out overnight, Korea down 11% and chipmakers 13%. Oracle sits one notch above junk at 6x leverage. Lepard adds $3.8T trapped in private equity and private credit, all mismarked.
Socialism for the rich. Frank Corva, reporting from New York, argues the US is not capitalist: Altman and Amodei asking Washington for stakes is the state picking winners. Cory's framing, via Saifedean, is that taking from everyone to give to your friends is the harder sell.
US versus China capitalism. Cory: America anoints monopolies and builds regulatory moats, while the CCP directs investment from the top then permits cutthroat competition. It happened in EVs and it is happening in AI. Open-weight Chinese models are the destabilizer.
A live bear debate. Gordon Johnson of GLJ Research brought three objections: private money has failed before, Bitcoin is not a real asset, and fixed supply breaks an economy. Cory and Lepard countered that a protocol with no issuer is not private money.
First duress-code prosecution. Samuel Tunick, an American citizen, was pulled into secondary inspection at Atlanta, pressured for his phone passcode, and entered a GrapheneOS duress code that wiped it. He is now charged federally with destroying property to prevent seizure.

How both guests actually cope Jeff sees an eerie replay of the 1930s and admits a libertarian may not fit where this is heading. Brandon Quittem urged empathy for those with no stake in the system, citing Naval that societies coordinate by free market or by force. Both landed on going outside and thinking local
The libngu decision, traced. An audience question surfaced that the firmware was rewritten off a GPL library partly out of anger at being cloned, producing an in-house source-available replacement and fewer eyes. Of 300-plus repos the red team has scanned, the one that came back completely clean was libsecp256k1.
The synthesis, and the way out. Suz: Bitcoiners who believe they saw through the system struggle to admit deception, because it means admitting they were fooled. Brandon: that lowers the guard rather than raising it. His prescription is local, not global. Be the sewer rat yourself.
Yan's read on whether this repeats.
Government overreach, the other half of the show. Suz on Liechtenstein's beneficial ownership register, roughly 31,000 entities, built in 2021 for EU anti-money-laundering compliance and now breached and offline. Yan on the Bank Secrecy Act's 1970 threshold, never inflation-adjusted, capturing dramatically more data for near-zero measured effect.
The AI incentive argument. Phillip's case: calls to regulate AI harder are moat-building, not safety, and defenders keep having to reach for open-weight models because the US frontier models refuse legitimate security work. Steve noted five figures a day in tokens is not a sustainable audit model.
Open source, and the AI asymmetry. Researchers keep reaching for Moonshot's open-weight Kimi K3 because US frontier models refuse legitimate security work. Rob Hamilton's decentralized effort to pentest Bitcoin repos received grant funding during the show.
Swan's status and the scam wave. Yan confirmed Swan Vault is built on Blockstream Jade and unaffected, and reported an influx of deposits. He flagged a devious scam variant where attackers send you working seed words and ask you to deposit into them.
Closing round on first resources. Inventing Bitcoin by Yan Pritzker, including his family's story of carrying value out of Russia. Also the Bullish Case, Broken Money, swan.com/welcome with Natalie Brunell, and Mary Kay Fain's approach: ask someone to recall a time they couldn't use their own money.
Adoption from the actual front lines. Corva on the Kibera slum's Afribit circular economy, single mothers saving for college, India cracking down on BitChat alongside Signal and Telegram, and Indonesia approving Fedi ecash. His hill to die on: Bitcoin is money.
